  Perfectionnement aux girobroyeurs La présente invention concerne Les machines destinées à La coupe des refus dans Les prairies, appelées girobroyeurs ou tondeuses de refus et munies de rotors ou couteaux rotatifs à axe vertical. 



  De telles machines sont connues mais dans des Largeurs de coupe assez réduites et pourvues de rotors disposés sur une ligne de coupe constante. 



  Le but de L'invention est de mieux épouser Les irréguLarités du terrain en gardant une coupe très uniforme. 



  Un autre but de L'invention est de créer une tondeuse de refus d'une grande largeur de coupe tout en permettant son déplacement sur route. 



  Une machine appelée girobroyeur ou tondeuse de refus réalisée suivant L'invention est caractérisée en ce que à un châssis principal pourvu d'un ou plusieurs rotors ou couteaux rotatifs est articulé à une ou à ses deux extrémités dans la largeur de coupe un châssis pourvu également d'un ou plusieurs rotors 

 <Desc/Clms Page number 2> 

 ou couteaux rotatifs. 



  Suivant L'invention également l'articulation entre le châssis principal et Le châssis articulé est située plus ou moins à hauteur de La ligne de coupe des rotors du châssis principal. 



  Encore suivant L'invention Le châssis articulé est repliable vers Le haut dans La voie du tracteur. 



  Pour mieux faire comprendre l'invention celle-ci est décrite maintenant sur la base du dessin annexé, à titre d'exemple uniquement, montrant en : Figure 1 une vue schématique en élévation d'une tondeuse de refus suivant L'invention en position déployée et sur un sol Lisse, et Figure 2 une vue analogue à celle de figure 1, la tondeuse de refus étant représentée en position repliée et en position de travail sur un sol non uniforme. 



  La tondeuse de refus représentée au dessin comporte un châssis fixe principal 1 pourvu de l'accrochage courant à un tracteur avec cardan 2 pour la transmis-   sion à partir de celui-ci   vers un ensemble de deux rotors 3 à axe vertical portés par ledit châssis. 



  A ce châssis principal 1 est relié, dans la largeur de coupe, un châssis complémentaire 4 suivant une articulation 5 située plus au moins à hauteur de la ligne de coupe des rotors 3. 



  Le châssis 4, articulé en 5 sur Le châssis   1,   est 

 <Desc/Clms Page number 3> 

 pourvu également d'un ensemble de deux rotors 3'à axe vertical, dont la ligne de coupe se confond avec celle des rotors 3, Lorsque La tondeuse se trouve sur un sol uni (figure 1). 



  La châssis 1 est porté par un patin 6 à chacune de ses extrémités et Le châssis 4 à son extrémité libre est également porté par un patin 6'. 



  La transmission aux rotors 3'du châssis articulé 4 est réalisée par un cardan téléscopique 2'. 



  Comme on Le voit en figure 2, Lorsque La tondeuse de refus se trouve sur un sol inégal, La partie articulée 4 peut suivre Les   irrégularités   du sol et épouser constamment Les dénivellations du terrain en permettant ainsi à La tondeuse de garder une coupe très uniforme avec une ligne de coupe brisée. 



  Bien entendu les châssis 1 et 4 peuvent être équipés d'un ou plusieurs rotors et Le châssis fixe principal 1 peut être   associé à un châssis articulé   4 à chacune de ses deux extrémités dans la largeur de coupe. 



  En réalisant une tondeuse de refus avec un ou deux éléments articulés on obtient une tondeuse faisant saillie hors de la voie du tracteur. Pour permettre Le déplacement d'une telle tondeuse de refus sur la voie publique, il est prévu suivant l'invention de relierlechâssisprincipal1aveclechâssisarticulé 4 par un vérin hydraulique   7,   grâce auquel Ledit châssis articuLé peut être replié vers Le haut dans La voie du tracteur (figure 2), ceci étant rendu possible également grâce au cardan téléscopique 2' 

 <Desc/Clms Page number 4> 

 des rotors 3'. 



  Grâce à L'invention on obtient La largeur de coupe de deux ou trois petites tondeuses de refus courantes, on garde une coupe très uniforme en épousant mieux Le terrain et on réalise un repliement dans la voie du tracteur avec un déport arrière minimum.

  The present invention relates to machines intended for cutting refusals in meadows, called rotary cutters or mowers of refusal and provided with rotors or rotary knives with vertical axis.



  Such machines are known but in fairly reduced cutting widths and provided with rotors arranged on a constant cutting line.



  The object of the invention is to better match the irregularities of the ground while keeping a very uniform cut.



  Another object of the invention is to create a rejection mower with a large cutting width while allowing its movement on the road.



  A machine called rotary cutter or rejection mower produced according to the invention is characterized in that a main frame provided with one or more rotors or rotary knives is articulated at one or at its two ends in the cutting width a frame also provided one or more rotors

 <Desc / Clms Page number 2>

 or rotary knives.



  According to the invention also the articulation between the main chassis and the articulated chassis is located more or less at the level of the cutting line of the rotors of the main chassis.



  Still according to the invention The articulated chassis is foldable upwards in the track of the tractor.



  To better understand the invention, it is now described on the basis of the appended drawing, by way of example only, showing in: Figure 1 a schematic elevation view of a rejection mower according to the invention in the deployed position. and on Smooth ground, and Figure 2 a view similar to that of Figure 1, the refusal mower being shown in the folded position and in the working position on non-uniform ground.



  The rejection mower shown in the drawing comprises a main fixed chassis 1 provided with the current attachment to a tractor with cardan shaft 2 for transmission from the latter to a set of two rotors 3 with vertical axis carried by said chassis .



  To this main chassis 1 is connected, in the cutting width, a complementary chassis 4 along a hinge 5 located more or less at the height of the cutting line of the rotors 3.



  Frame 4, articulated in 5 on Frame 1, is

 <Desc / Clms Page number 3>

 also provided with a set of two rotors 3 ′ with vertical axis, the cutting line of which merges with that of the rotors 3, when the mower is on level ground (FIG. 1).



  The chassis 1 is carried by a shoe 6 at each of its ends and The chassis 4 at its free end is also carried by a shoe 6 '.



  The transmission to the rotors 3 ′ of the articulated chassis 4 is carried out by a telescopic gimbal 2 ′.



  As seen in Figure 2, When the rejection mower is on uneven ground, the articulated part 4 can follow the irregularities of the ground and constantly follow the unevenness of the ground thus allowing the mower to keep a very uniform cut with a broken cut line.



  Of course the chassis 1 and 4 can be equipped with one or more rotors and the main fixed chassis 1 can be associated with an articulated chassis 4 at each of its two ends in the cutting width.



  By making a rejection mower with one or two articulated elements, a mower protruding out of the tractor's track is obtained. To allow the displacement of such a refuse mower on the public road, it is provided according to the invention to connect the main chassis 1 with the articulated chassis 4 by a hydraulic cylinder 7, by means of which said articulated chassis can be folded up in the path of the tractor (FIG. 2), this being made possible also thanks to the telescopic gimbal 2 '

 <Desc / Clms Page number 4>

 3 'rotors.



  Thanks to the invention, the cutting width of two or three small current refusal mowers is obtained, a very uniform cut is kept while hugging the ground better and a folding in the track of the tractor is carried out with a minimum rear offset.
